To all whom it may concern:

Be it known that I, Ennnsr Dusoi-inn, a citizen of the United States, residing at La Crosse, in the county of La Crosse and State of WVisconsin, have invented a new and useful Improvement in Printingh Iachines, of which the following is a specification.

My invention relates to improvements in printing machines and its object is to provicle improved means whereby letters having difi'erent names and post oifices of addressees and envelops having addresses corresponding with said names and post oifices in the letters may be printed successively. In carrying this invention into use a typebed is employed which may be introduced on the main type bed of a printing machine in connection with the type form thereon to carry a supplementary form exchangeable and adjustable with relation to the other forms carried by the machine. In connection with this object my invention is adapted to the insertion and removal of supplementary type forms such as are used in printing different names and post ofiices of addressees on copied letters, to the printing of said names and post oflices on envelope and to the positioning ofthe paper and envelops in the machine over the type form so as to register letters or envelops accurately over the type form and portions thereof.

This invention is simple in construction and effective in operation, the particular adaptability of the construction illustrated being especially appropriable but not necessarily confined to use in connection w th the apparatus described in my companion application Serial No. 660,425 filed on November 15, 1911, for filling in attachment for printing machines.

In the drawings with which I have illustrated my invention and which form part of this specification, Figure 1 is a plan view of a printing machine of the class mentioned equipped with my improvement; Fig. 2 is a sectional view on the line XX, Fig. 1 showing a side elevation of my imp-rovement; Fig. 3 is an enlarged sectional view of a detail showing a portion of the type bed and of the form thereon also a portion of the ribbon and of the parts which are employed for positioning envelops over the type form; Fig. 4 is a side elevation of a detail, portions thereof being broken away showing an envelop lifter and spacer; Fig.

Fig. 6 is a side elevation of the envelop guide which assists in positioning the envelop laterally on the filling in block; Fig. 7 is a plan of one of the impression rollers; Fig. 8 is a plan of the filling in type block; Fig. 9 is a sectional side elevation of the construction illustrated in Fig. 8; Fig. 10 is an enlarged detail of a portion of Fig. 9 in a different position of the parts; Fig. 11 is a perspective of the supplementary type holder or name plate; Fig. 12 is a perspective of a detail showing means whereby a separate adjustment of each platen roller is provided, the carrier chain being broken away and the two platen rollers shown close together for the purpose of illustration; Fig. 13 is a perspective of an alternative form of the envelop lifter and spacer; Fig. 14 is a perspective of a detail of a portion of the construction illustrated in Fig. 13; Fig. 15 is an enlarged sectional view of a detail of the bed of the machine showing the skid rails illustrated in Fig. 12 and the envelop lifter and spacer illustrated in Fig. 13 applied thereto in connection with the type form and type block; Fig. 16 is a side view of one of the skid rails illustrated in Fig. 12, and Fig. 17 is a longitudinal section through the machine showing the construction of envelop lifter and spacer illustrated in Fig. 13 applied thereto.

Inthe above drawings 1 have shown a printing machine having a frame A, a type bedB carried by said frame, on which a form C may be supported and with which a platen D cooperates in making a printing impression. E indicates a supplementary type bed or type block which is shown mounted on the main type bed B in the main form C and carries a supplementary type holder or name plate F which is adapted to be so positioned on the type block E as to cooperate with the platen D in the same manner as the main form C on the type bed.

On the frame A are mounted sprocket wheels 2 carrying sprocket chains 3 at each side of the machine, 011 which is mounted a platen D in the form of a roller having a body 4 which traverses the type form and a wear wheel 5 at each end through which printing pressure is imparted to the platen. The type bed B is so positioned with relation to the path of the platen D carried by the sprocket chains 3 that normally it travels orbitally about the type bed and above the surface of the type in the form and out of contact with it. H

Printing pressure on the platen is secured l by means of bars 6 at each side of the machine under pressure from the springs 7 which may be adjusted to different degrees 7 r of pressure. The under surface of each of gighe pressure bars 6 is formed with notches 8 bearing upon the periphery of the wear wheels and producing intermittent and repeated" impacts on the platen and thereby on the type in the form. V

' A skid bar 9 is shown at each side of the machine on which travels the wear wheels 5; The skid bars are mounted upon supporting pins 10 (see Fig. 3) which play ilooselythrough the bed of the machine and upon which springs 11 are mounted between the-rails and the bed, the tendency of these springs being'to raise. the bars. Stop nuts 12 on the lower ends of the pins limit the upward movement of the bars, the tension of the springs 11 being such that normally when the platen roller is not pressed into cooperation with theotype on the form in the machineby the pressure bars the skid bars supporttherplaten roller so that it will ride above and out of cooperation with the type'in the form.

A color inking ribbon 13 is carried in the machine between the path of the platen and the type form and is passed over suitable spools 14 connected by gears 15 with the sprockets 2. Idle rollers 16 are also journaled in the frame of the machine over which the ribbon travels in its path around the type form and onto the spools. The ribbon is adapted to be stepped forward after each stroke of theplatens in the usual manner by any suitable mechanism of ordinary construction. An operatmg handle 17 connected with one pair of sprockets 2 operates the belts 3, platen D and ribbon 13.

My supplementary type bed or prlnting block E consists of a body part 18 of comparatively narrow width and extending transversely across the type bed and parallel with the line of orbital motion of the platen D. The body 18' rests horizontally on the type bed B on which it is adjustable vertically by means of set screws 19, this adjustment being'permanent when once made to bring the raised portion 20 of the type block to such an elevation that standard type 21 in the supplementary type form Fliave an equal elevation with the type commonly pusher.

or above these parts of the body 18 do not have printing contact with the ribbon 13 during the passage of the platen D. The lateral sides of the body 18 are formed with grooves 22 extending the full length thereof for the engagement of the name plate F which is formed with lugs 23 adapted to travel in the grooves 22 during the longitudinal movement of the plate F along the printing block. The lugs 23 extend down the sides of theprinting block and into the grooves 22 and allow thetype 21 carried by the name plate to rest upon the raised portion 20 when the name plate reaches that part of the block.

A spring 25 on the side of the printing block serves to hold the address plate in printing position on the raised portion 20 of the block, the movement of the plate being at all times controlled by the operator who is able to move the plates in series into printing position by hand as fast as they are required during the operation of the machine. The extension 27 having the same width as the block E permits the name plates to be pushed from the block and from under the color ribbon 13. The movement of the plates 1* along the block is accomplished by means of the pusher 28 which slides in a slot 29 in the block on the rod 30. This rod 30 is mounted on the block and carries a spiral compression spring 31 in front of the pusher 28 said spring being compressed by the pusher during the forward movement thereof in advancing the plates. Upon releasing the pusher the spring 31 returns it sharply and automatically to its original position. In order to se cure the engagement of the name plate F by the pusher a spring stop 32 is mounted in the This stop is adapted to recede out of the path of the paper upon the form when the pusher is released and its construction and operation are fully set forth in my companion application above referred to.

To prevent the interference of the plates F and the ribbon 13 during their advancement along the block E the ribbon is automatically held out of contact with the plate by means of a spring 35 positioned longitudinally of the block E and near the side of the ribbon adjacent to the approach of the block. This spring stands above the level of the type in the plate and normally keeps the ribbon raised therefrom. It is however a comparatively weak spring permitting the platen to spring the ribbon into contact with the type without resistance and is formed of smooth Wire to permit the unobstructed travel of the ribbon.

The name plate or supplementary type form F has the form of a plate with a series of slots 36 in which are mounted suitable double shoulder type 21 adapted to engage the sides of the slots for support to prevent lateral movement of the type when in print ing position and to hold the type assembled when not being used in the machine. The type are placed in the slots in suitable form for printing the names and post offices of addressees, salutations, and the like and are locked in the slots as by compressing the shoulders of the type at the end of the series.

In addition to the platen roller D having a body the length of which extends over the entire type form including the changeable type carried by the insert or name plate, a supplemental platen D is used which is of similar construction to the platen D excepting that its impression surface is limited in length so as to traverse over only the type carried by the filling in type holder or name plate composing the name and address of the addressee. The supplemental platen roller is carried by the chains or belts 3 and is evenly spaced from the platen element D on the belts so that the impressions made by the rollers D and D are at even intervals.

In Fig. 12 the platens are shown close together only for illustrative purposes.

A system of paper guides is employed for assisting in positioning sheets of paper over the entire type form including the name and post oflice of the addressee, and envelops or sheets of printing material over said name and post office only or that portion thereof which may be used for addressing purposes. This system is so constructed that the sheets or envelops are raised automatically to assist the removal of the printed material from the machine. The sheets of printing material which receive an impression from the entire type form including the names and post offices of the addressees are positioned by means of the side guides G and the longi tudinal guide H, while the printing material such as envelops which receives only the name and address of an addressee from the type in the name plate is positioned by the side guide I and the longitudinal guide J.

The guides G- each of which is in the form of clips or jaws 37 rest with their lower arms 38 upon the ribbon above the type form and are adjustable longitudinally and transversely so that they may be placed in suitable position above the type form to position sheets of printing material accurately upon the ribbon above the form. The jaws of the paper guides G are received together in the socket member 39 upon an arm 40 to which the jaws are secured in longitudinally adjusted position by means of a clamp 41. The arm 40 is formed on the side of the body piece 42 which is secured in transversely adjusted position upon a vertically reciprocable member 43 by means of a set bolt 44. Normally the paper guides G rest closely above the ribbon on the forwardend of the form out of the path of paper strippers K which are carried by the belts 3 and engage the printed material after each operation of printing in the machine and eject the material on the type form from the rear end of the machine toward which the rollers D and D travel. In order that the paper strippers K following the platen roller D may engage the forward edge of each sheet of printing material on the form, the paper guides G are reciprocated by the member 43 so as to automatically manipulate the sheet of printed material with its forward edge in raised position to be engaged by the strippers K. The member 43 has its ends 45 slidably mounted to move vertically in the bed of the machine and is lifted by means of lever arms 46 and connecting links 47 the former being fixed upon a shaft 48 which is journaled in the frame. The shaft 48 is rocked to tilt the levers 46 by means of a crank arm 49 and push rod 50. This push rod is actuated by means of a cam 51 carried by a large gear 52 journaled on the frame and driven by a pinion 53 which is mounted upon one of the shafts 54 carrying a pair of the sprockets 2.

The longitudinal paper guide H is in the form of a vertical plate resting by gravity upon the ribbon above the form and pivotally mounted at one end upon a sliding support 55 which is adapted to be secured in laterally adjusted position by means of a thumb screw 56 upon a transverse shaft 57, said shaft being mounted above the path of the platen elements on the frame. As the platen elements travel orbitally about the type form on the bed, the paper guide H is lifted by the platen elements out of their path of travel and drops by gravity in position upon the ribbon above the type form to act as a guide for one end of the sheet of printing material which is placed above the form to be printed and against the paper guides G.

The paper guides employed for positioning the envelops or the printing material which is to receive only the names and post ofiices of addressees from the filling in plates consist of members I and J. The guide I is in the form of a clip slanting upwardly which can be secured in longitudinally selected position upon the spring strip 58 by means of a screw 59 engaging in any one of the threaded openings 60 in the strip (see Fig. 5). The strip 58 is made of spring metal or other suitable material and one of its ends is hinged at 61 upon the end of the bar or block 62, the opposite end of the strip resting upon the bar and being held under tension or restrained by means of a tie bolt (33 passing freely through a horizontal web 64 formed across a recess 65 in the bar. The tie bolt 63 acts as a guide for the strip and carries an expansion spring 66 which augments the strength of the elasticity in the strip. The strip rests normally a short distance above the bar leaving a space through which the inking ribbon is free to feed over the type in the form and the filling in plates when the machine is in operation. The bar 62 is adapted to be locked in the form with the filling in block E upon the bed of the machine, the bar lying parallel to the filling in block and being disposed with the hinged end of the strip 58 near the forward end of the bed so that the platen element D passing upon the form will gradually impinge upon the strip 58 and press it down. As the platen element D leaves the form and the filling in plate of type, the strip 58 springs back into raised position releasing the ribbon. As the platen element D passes on to the form it rolls upon the strip 58 depressing it until the envelop is printed Whereupon the strip is released and the envelop raisedby the strip into position to be engaged by the strippers K which remove the envelop from the machine. It will be noted that the surface of the roller D is of suf- 'ficient length to cooperate with the type on the filling in plate and with the strip as above described.

The paper guide J which serves to assist in positioning the envelops in laterally selected position upon the type form consists of a plate 67 which is selectively positioned longitudinally upon thearm 68 of the crank 69 by a thumb screw 7 O. The crank 69 is adapted to be secured in longitudinally adjusted position upon a clip 71 by means ofa screw'72, said clip 71 being suitably placedupon one of the pressure bars 6 by means of the thumb screw 74. 1 By turning the crank 69 in the clip 71 and settingthe screw 72, the plate 67 can be regulated in height above the type form out ofthe path of the impression elements and by adjusting the crank 69 longitudinally in the clip '71 and the plate 67 upon the arm 68, the

plate can be regulated in position transversely above the type form. In positioning an envelop in the machine above the ribbon it is placed face downward with its forward extending end against the clip I and with one of its edges against the plate 67. The surface of the platen element D then engages the extending end of the envelop in the clip I and rolls over the envelop thus making a printing impression.

.A set of paper strippers K mounted upon a shaft 7 3' which is carried by the belts 3 at a suitable distance from each platen element is adapted to perform the function of removing the paper and the envelops as they are printed from the machine. The strippers K consisting of clips or jaws are adapted to engage the raisedforward edges of the sheets and envelope immediately after they have been printed. The strippers on the shaft 73 following the platen element D are positioned transversely so as to engage the sheet of paper evenly which has been printed so that it is projected from the machine in regular order. The strippers mounted upon the shaft which follows after the platen element D are also positioned so as to perform the same function regarding the envelops.

In operation a sheet of paper of sufficient size to receive an impression from the body of the form including the name and post oflice of an addressee and salutation, is placed in the machine and printed, it receiving an impression by the platen element D. The strippers remove the sheet of paper which has been printed and an envelop is then placed, face downward, over the filling in portion of the type and adjusted to the guides I and J. It in turn receives an impression from the platen element D and the strippers remove the envelop. The machine is then in readiness to repeat the operation, a new addressing plate being placed in the machine on the filling in block before another sheet of paper and an envelop are printed. It will be noted that a filling in plate is placed in the machine on the block after every two impressions are made by the plate rollers also that only the type in the main form and in the plate resting upon the raised portion 18 of the filling in block is adapted to deliver a printing impression. the type in plates on the lower surfaces of the type block resting below the plane of the remaining type in the form.

At the delivery end of the machine are placed paper delivery slides 76 secured to the frame and upon the bar ()2 is secured another paper delivery slide 77, the latter assisting in directing the envelops from the filling in block to produce unobstructei'l ad 11'.

justment of the plates on said block and to keep the ribbon when feeding out of contact with the type.

As illustrated in Figs. 1, 9. and 7 the wear wheels 5 are adapted to travel upon th surfaces of the single pair of skid bars 9. one bar being placed at each side of the type form on the surface of the bed while in Fig. 12 two skid bars are illustrated on each side of the bed. one for each platen roller whereby the platen rollers may be adjusted to travel with their impression surfaces in the plane of the type in the form and holder. In Fig. 12 the platen rollers are shown close together. the carrier shown being broken away for illustrative purposes only.

The bar 9 on which roller D travels is similar in construction to the bar 7 9 on which roller D runs except that bar 9 has a tabulating ribbon or strip 80 secured to its surface such as by screws 81. These bars are secured in parallel position longitudinal to the travel of the rollers D and D on each side of the form on the surface of the bed B with their supporting pins 10 playing freely through openings 82 in the bed. Each bar has a pair of vertically disposed screws 83 projecting downwardly therethrough by which the bars may be adjusted in height with their impression surfaces to the planes of the type in the type form and in the holder on the raised surface 20 of the type block. Perforations 84 in the ribbon provide access to the adjusting screws 83 in the bar 9 for turning them. The wear wheel 5 on roller D is formed with an annular space 85 over each bar 79 while roller 1) has its wheel 5 of less diameter over bar 9 than the portion thereof over 79, thus leaving a pair of skid bars coacting with each impression roller to regulate its plane of travel over the type form.

In Figs. 18, 14 and 17 a modification of the construction described for positioning the envelops or the printing material which receives the address portion from the filling in plates is'shown. The guide J in this construction for lateral positioning remains the same as described. The guide for positioning the envelops longitudinally over the type holder in printing position consists of a bar 86 and a strip 87 carrying the clip or stop 88, said bar being raised automatically after each printing operation by the vertically reciprocable member 43. The bar 86 is adapted to be clamped longitudinally in the type form alongside of the type block E and is formed with a downwardly slanting hollow rearward end having inturned upper edges 89 below which a shouldered end 90 of a strip 87 extending longitudinally on the bar 86 engages. The clip 88 can be secured to the strip 87 in longitudinally selected position by screws 91 engaged in any of the sets of threaded openings 92 in the strip. The strip conforms in angular shape to the surface and end of the bar 86 so that by moving the strip with its shoulders formed by notches 93 against the in turned edges 89 the strip is raised slightly above the surface of the bar leaving a space 94 through which the ribbon 18 is free to move and feed when the platen rollers do not cooperate with the type on the bed. The

forward end of strip 87 is secured adjustably to an arm 95 carried by member 43 by a bracket 96 on strip 87 and an adjusting screw and nut 97 and 98. By tightening the nut 98 the strip is moved longitudinally and raised by its shouldered end being moved up the inclined end of the bar 86 and by loosening the nut the operation is reversed and the space 94 diminished.

As the rocker arm 46 is swung up and gage the forward edge of the envelop and remove the envelop from the machine. The guide pin 99 on the arm 95 passes through bracket 96 and assists in preventing side motion of the strip when raised. The bar 86 may be adjusted in height on the bed of the machine by screws 100 threaded downwardly through the bar.

In accordance with the patent statutes I have described the principles of operation of my invention together with the apparatus which I now consider to represent the best embodiment thereof but I desire to have it understood that the construction shown is only illustrative and that the intvention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.
